How to be sure to get rid of lice? - briefly
Effective elimination requires applying an approved pediculicide, combing out all nits with a fine-toothed lice comb, and laundering bedding, clothing, and personal items in water ≥ 60 °C. Re‑treat after seven days to ensure any newly hatched parasites are eradicated.
How to be sure to get rid of lice? - in detail
Lice infestations require a systematic approach that eliminates the insects and prevents re‑colonisation.
First, confirm the presence of live nits or adult lice by inspecting the scalp with a fine‑tooth comb. Separate each strand, pull the comb from the root to the tip, and examine the comb teeth for moving insects or oval, brownish eggs attached within ¼ inch of the scalp.
Second, apply an approved pediculicide according to the product label. Options include dimethicone‑based lotions, pyrethrin‑containing shampoos, or prescription ivermectin. Apply the solution to dry hair, saturating the scalp and shaft, leave for the specified duration, then rinse thoroughly.
Third, repeat the treatment after seven to ten days to target newly hatched lice that survived the first application.
Fourth, remove residual nits mechanically. After each treatment, comb the hair with a fine‑tooth nit comb while the hair is still damp. Perform the combing process in sections, repeating until no nits are detected for three consecutive sessions.
Fifth, decontaminate personal items and the environment:
- Wash bedding, hats, scarves, and clothing in hot water (≥ 60 °C) and tumble‑dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags promptly.
Sixth, monitor the scalp daily for two weeks. If live lice reappear, repeat the full treatment cycle.
Seventh, implement preventive measures: avoid sharing combs, hair accessories, hats, and bedding; discourage head‑to‑head contact in group settings; and conduct routine inspections in environments where lice are common.
Adhering to this protocol eliminates the current infestation and reduces the likelihood of recurrence.
